The Australian Consumer Law (ACL) prohibits businesses from engaging in 'unconscionable conduct' in their dealings with consumers and other businesses.
Engaging in this conduct can lead to penalties of up to the greater of $10 million, 3 times the value of the benefit received, or where the benefit cannot be calculated, 10% of annual turnover in the preceding 12 months for a corporation and $500,000 for an individual.
